The paddle-tailed darner (Aeshna palmata) is a species of dragonfly in the family Aeshnidae. It is common throughout western Canada and United States. This species is named after its distinctive paddle-shaped appendages. It lives in many habitats, particularly lakes, ponds, and slow streams, usually with dense shore vegetation. Aeshna palmata was scientifically described for the first time in 1856 by Hermann Hagen. Wikipedia →

Rare
Under 5% of wildlife watchers report a Paddle-Tailed Darner sighting in Portland on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 378th most-seen of the 507 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Paddle-Tailed Darner in Portland on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Paddle-Tailed Darner sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 6 cities where we can rate Paddle-Tailed Darner sightings, Portland ranks 6th at under 5%, level with the leaders once rounded. The best odds are in Denver (United States, under 5%), Seattle (United States, under 5%) and Vancouver (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Paddle-Tailed Darner is recorded against all the insects logged in Portland (9 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
